AI agent that autonomously codes from midnight to 7 AM, opening production-ready PRs by morning.
README
Overview
Overnight Coder picks up tasks from your backlog at midnight and works through them while you sleep. It reads your codebase to match existing patterns, writes tests, makes clean commits, and opens well-documented pull requests. By 7 AM you get a morning report with everything that shipped and anything that needs your input.
